Abstract
A collapsible three-dimensional construction in the form of a cube is described. The construction is formed of paperboard, pasteboard, cardboard plastic or similar material. The cube may be formed from a single sheet of die-cut material. Four of the faces of the cube include perforation lines to allow the cube to be collapsed into a flattened cube when twisted about a central axis in a first direction. Two elastic members are attached to tensioning members inside of the cube and serve to hold the cube in an erected position when twisted in a second, opposite direction. The assembly of the cube from the blank requires only a single fastening of one portion of the construction to another. The surfaces of the cube may be easily printed with advertising or promotional material.
